You are corect on the line/area just plummeting but it's a lot better then
showing a line at the bottom of the graph. Not to mention with a small
change to the code you can still graph the 0 values but remove the none 0
values.

=IF(ISERROR(VALUE(A1)=0),-100,VALUE(A1))

This will allow you to graph the true 0 values but leave out the none 0
values.

Hi Mike,

I can see how the actual point would not show when set to -100 and the
minimum y axis value set to zero. But that does not stop the line
between points plummeting to the base line and then re surfacing a bit
further along.
Or are your line charts just points?

Cheers
Andy

Ok got this to work for Line and bar graphs haven't tried anyothers yet.
The pesky problem of yoru graphs always plotting 0 or none 0 values
(#N/A...) as 0 can be hidden in a very sneeky way. Fish off in yoru chart
put a IF statement that if the value is greater then 0 everything goes as
normal, but if it's False then enter in a value like -100. Then on yoru
graph set your Y-axis Minimun to 0. the -100 Data value will be off the
graph and won't show up. Like I said very sneeky.

If statement used.
=IF(A10,A1,-100)
